This RVGUARD adapter bridges that gap and adds multiple built-in safeguards so you can plug in confidently. It’s designed specifically for RV use, constructed with heavy-duty materials, and carries an ETL full-product listing to meet safety expectations.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this adapter protect my RV’s electrical system?\u003c\/h3\u003e\n\u003cp\u003eThe adapter combines surge suppression and an overload trip to reduce the risk of damage from voltage spikes or drawing too much current. A 3600-joule surge absorber mitigates short-duration high-voltage events, while an internal circuit breaker interrupts power if the load exceeds 30 amps.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e3600 joules of surge energy absorption to lessen spike damage\u003c\/li\u003e\n  \u003cli\u003eBuilt-in resettable circuit breaker that trips on overloads\u003c\/li\u003e\n  \u003cli\u003eLED power indicator to show when power is present and protected\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill it fit my RV and campground outlets?\u003c\/h3\u003e\n\u003cp\u003eThis cord is a 30A (NEMA TT-30P) male to 50A (NEMA 14-50R) female adapter, allowing a 50 amp RV cord to connect to a 30 amp pedestal.
